can timers interrupt my code?

[jes presto med upenn edu]

Do timeout callbacks interrupt drawing code?  I mean, in my configure
callback (e.g.), do I need to worry about the drawing code being
interrupted by a timeout which shares some data?

Same for input functions?

GGAD isn't explicit on this (sorry if I missed it), but it describes
both of these under 'The Main Loop', which implies that they are run
from the main loop, and not completely asynchronously.
